Excel VBA 实现SQL数据读取K3人员信息
Private Sub CommandButton1_Click()
Worksheets("Sheet2").Select
Cells.Select
Selection.Delete Shift:=xlUp
Range("A1").Select
'清除在Excel中的数据,确保导入信息不出现与原Excel数据进行叠加
Dim cnnConnect As Object
Dim rstRecordset As Object
Columns("A:C").Select
Range("A1").Activate
Selection.Delete Shift:=xlToLeft
Set cnnConnect = CreateObject("ADODB.connection")
Set rstRecordset = CreateObject("ADODB.Recordset")
cnnConnect.Open "Provider=SQLOLEDB;" & _
"Data Source=10.11.1.4;" & _
"User ID=finWork;Password=finwork;"
rstRecordset.Open _
Source:="Select code, name, email from hm_employees where status=1", _
ActiveConnection:=cnnConnect
'建立数据库连接,Source为数据库数据服务器IP,及连接用户名与密码,在实现时确保用户对K3数据库有读取权限
With ActiveSheet.QueryTables.Add( _
Connection:=rstRecordset, _
Destination:=Range("A1"))
.Name = "Contact List"
.FieldNames = True
.RowNumbers = False
.FillAdjacentFormulas = False
.PreserveFormatting = True
.RefreshOnFileOpen = False
.BackgroundQuery = True
.RefreshStyle = xlInsertDeleteCells
.SavePassword = True
.SaveData = True
.AdjustColumnWidth = True
.RefreshPeriod = 0
.PreserveColumnInfo = True
.Refresh BackgroundQuery:=False
End With
'导入K3数据到Excel中,
Range("A1").Value = "工号"
Range("B1").Value = "姓名"
Range("C1").Value = "Email"
ActiveWorkbook.Worksheets("Sheet2").QueryTables
